Perform EVAP tester self-test

WARNING: This page is about a different car, the 1999 Audi A8, 1998 Audi A8, and 1997 Audi A8. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Always perform system self-test of KLI9210 EVAP Tester prior to use to ensure that there are no leaks.
Refer to KLI9210 instruction manual for specific instructions.

Connect vehicle interface hose to self-test port -1-, ensuring that fitting is finger-tight. Over-tightening will damage fitting.
Turn control valve -2- to "Test".
Gauge -3- should read 14 + 1 in. of water.

If gauge does not read 14 + 1 in. of water:

Verify that valve on EVAP tester nitrogen cylinder is open and that cylinder has sufficient pressure before continuing.
Turn fine adjust regulator knob (arrow) until gauge reads 14 in. of water; tighten lock nut.

NOTE: If gauge still does not read within above range, contact K-Line Customer Service - Technical Support for additional instructions before continuing.

Check flow meter -4-. (upper illustration).
Meter must indicate no flow.
Turn control valve to "Hold" position.
Check gauge.
Gauge must hold pressure

If gauge leaks down:

Verify that vehicle interface hose is firmly seated and repeat previous six steps before continuing.

If gauge continues to leak down:

Use ultrasonic tester (described later) to locate and repair leak before continuing.

NOTE: If the leak cannot be located or repaired, contact K-Line Customer Service - Technical Support.
